• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chau tinh) OR (ha tinh)) - ((hanh trong) or (hanh trang)) van nang cong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chau tinh) OR (ha tinh)) - ((hanh trong) OR (hanh trang)) van nang cong dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chau tinh) OR (ha tinh)) - ((hanh trong) or (hanh trang)) van nang cong dan toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chau tinh) OR (ha tinh)) - ((hanh trong) or (hanh trang)) van nang cong dan toan cau*.
